Definitions
- the invention relates to a method for displaying the position and orientation of a tool for preparing a femur for a femur implant engaging with a joint ball in the acetabulum of the pelvis or in a pelvis inserted in the pelvis, or such a femur implant to be inserted into a femur relative to the femur and Center of the joint ball.
- a femoral implant In hip joint surgery, it is necessary to insert a femoral implant into the femur after the head of the femur has been removed.
- the femoral implant is usually adapted to the natural course of the bone and has a leg insertable into the femur, an obliquely departing femoral neck and thereon a ball joint which engages the acetabulum of the pelvis, either in the natural or in most cases in an artificial acetabulum.
- the femoral implant For insertion of the femoral implant into the femur this must be prepared, and it is customary to accomplish this with the help of rasp-like tools that prepare the medullary canal of the femur so that the shaft of the femoral implant can be inserted into the femur fit, ie such that the implant assumes the desired position and orientation relative to the femur, so that correct positioning of the femur takes place when the joint ball of the femoral implant enters the acetabulum.
- This object is achieved erf ⁇ n- tion in a method of the type described above, that is in a transverse plane of the femur at the level of the center of the joint ball this and a line of intersection of this transverse plane and an instrumental level, which passes through the center of the ball joint.
- the surgeon can thus see on the screen once the center of the joint ball and on the other hand, the cutting line, which indicates to him at what angle in the transverse plane intersects the instrument level.
- the instrument level may be a level of a surgical, rasp-like instrument, but the instrument level may also be a level of the femoral implant.
- the instrument level may be provided that one chooses the instrument level so that it is the median plane of the tool.
- the shafts and then the corresponding rasp-like tools have an oval or oblong cross-section, the long axis pointing in the direction of the femoral neck of the femoral prosthesis, ie in the direction of the joint ball.
- this longitudinal medial plane of the shaft is used as the instrument plane, it is ensured that this plane passes through the joint ball and thus indicates to the surgeon how the direction from the shaft to the point of articulation in the transverse plane runs.
- the function of the joint center it may be provided according to a preferred embodiment that in the representation of the transverse plane of the femur and the cutting line, an image of a transverse section of the pelvis at the level of the center of the joint ball receiving acetabulum so copied, that the center of the joint ball and the center of the acetabulum coincide.
- the transverse plane is a plane which passes through the two centers of the acetabulum and runs horizontally when the patient is standing upright. It can be a cross-sectional view, but also about a top view of the pelvis, in which the position of the center of the Acetabu- lum is made visible by the fact that the pelvis is shown partially transparent. It is only essential that the surgeon symbolically shows by this representation that the joint center of the femur is located in the acetabulum of the pelvis.
- the transverse plane of the femur To locate the transverse plane of the femur, one can preferably determine the position and orientation of the center of the joint ball and the knee joint, for example by palpation of the patella, and also as the connecting line of the two points of the mechanical femur axis, the transverse plane is then perpendicular to this mechanical axis femur and passes through the center of the ball joint.
- the surgeon can see in the described representation in the change of position and orientation of the tool and / or the femur implant immediately as the intersection between the instrument plane and transverse plane of the femur shifts, with a rotation of the shaft of the machining tool or the femur implant, the angle change this section line in the presentation, with a lateral displacement of the tool shank or the implant shaft without rotation, the line will move parallel to itself.
- a correct position and orientation of the tool shank and the femoral implant shaft is obtained when the cutting line passes through the image of the center of the joint ball. Since the instrument plane itself passes through the center of the joint ball, this indicates to the operator that both the angular orientation and the lateral displacement of the tool shaft or the femoral implant shaft are correctly selected.
- the invention is also based on the object to provide a device for carrying out this method.
- a device with a navigation system with this associated marking elements for the femur, for the pelvis and for the tool or the femur implant, further by a data processing system and activated by this display, wherein it is provided that the Data processing system is programmed so that it represents on the display in a transverse plane of the femur at the level of the center of the joint ball this and a line of intersection of the femoral transverse plane and an instrumental plane passing through the center of the joint ball.
- the data processing system is programmed to select the center plane of the tool as the instrument plane.
- the data processing system may be programmed to select as the instrument plane the projection of the longitudinal axis of a holding arm connecting the shaft of a femoral implant or a tool with the joint ball to the transverse plane in the instrument plane.
- the data processing system is programmed so that it copies an image of a transversal section of the pelvis at the level of the center of the joint ball receiving acetabulum in the representation of the transverse plane of the femur and the cutting line so that the center of the joint ball and the center of the acetabulum coincide.
- the data processing system may further be programmed to determine a mechanical femoral axis for locating the transverse plane of the femur from the position and orientation of the midpoint of the joint ball and knee joint as the connecting line of the two points and the transverse plane as perpendicular to this mechanical femur axis and through the midpoint the joint ball is calculated going.
- Figure 1 a schematic view of the pelvis and the femur of a patient and a navigation system with a data processing system and with a display;
- FIG. 2 shows a schematic view of the pelvis and a part of the femur with an inserted and navigated machining tool, indicating the femoral transversal plane and the instrument plane;
- FIG. 3 shows a view of the display with a representation of the intersection of the femoral transversal plane and the instrument plane, the center of the condyle and a copied-in representation of the pelvis;
- FIG. 4 shows a cross-sectional view of the shank of a rasp-like machining tool according to line 4-4 in FIG. 2; 5 shows a schematic side view of a femoral implant with a shaft, a femoral neck and a joint ball and
- FIG. 6 shows a sectional view of the femoral implant of FIG. 5 along line 6-6 in FIG. 5.
- the method according to the invention is used to prepare the femur 1 of a patient for the admission of a femoral implant or to insert a femoral implant into it. This is necessary in a hip joint operation where the natural hip joint is replaced by an artificial socket in the pelvis and a femoral implant with a ball of joint inserted into the remaining femur after removal of the natural femoral head in its place.
- the femoral implants usually have a shaft which is driven into the medullary canal of the femur, and this medullary space must be prepared accordingly, this preparation is carried out with the aid of a rasp-like tool 2, which is very similar to the shaft of the femur implant and the medullary canal of the femur 1 is prepared in such a way that the insertion of the stem of the femoral implant determines the positioning of the femoral implant in the femur by the geometry of the prepared medullary cavity.
- the tool 2 is driven into the femur in exactly the desired angular orientation and lateral position during the preparation of the femur, and of course it is essential to place the femoral implant in the correct position in the femur.
- Correct position means that the laterally projecting arm of the femoral component, which usually carries at its end a ball joint, relative to the pelvis and the socket in the pelvis takes the correct orientation.
- the surgeon knows where to position the condyle relative to the natural femur, and the geometric data of the femoral implant are known, so that when inserting the femoral implant into the femur, it is always possible to determine the position of the femur implant in the femur to which position of the condyle leads.
- a marking element 3, a marking element 5 and a marking element 7 on the pelvis 4 are permanently and rigidly attached to the femur 1, wherein the tool 2 could be replaced in the same way by the femoral implant. In the following therefore will be spoken only by the tool 2.
- the position of the marking elements 3, 5 and 7 can be determined by means of a navigation system 8 known per se, which has, for example, three spatially separate transmitters 9, 10, 11 which emit infrared radiation emitted by spatially separated reflectors of the marking elements 3, 5, 7 reflected and from the working as a receiver transmitters 9, 10, 11 is collected again. From the radiation both the orientation and the position of the marking elements can be calculated in space, so the location of each marking element. Since the marking elements are rigidly connected to the femur, the pelvis or the tool, so that the respective position of the marking elements in the room to determine at any time.
- the corresponding location data sets are supplied by the navigation system 8 to a data processing system 12, which uses this data for the calculation of further data and, among other things, can generate a visual display on a screen 13.
- a data processing system 12 uses this data for the calculation of further data and, among other things, can generate a visual display on a screen 13.
- the position of the knee joint is determined, this can be done by palpation with the aid of a provided with a marker element 6 probe element 14, which is applied with its tip, for example, to the patella of the patient.
- the data processing system can calculate from the position data of the navigated probe element 14 and the geometric data of the exact location of the palpable marker point on the patella, which is used as a knee joint point.
- the data processing system then forms the connecting line of the center of the condyle and the knee joint, this connection line is referred to as a mechanical femur axis 15.
- the data processing system 12 further calculates a femur transverse plane 16 perpendicular to the mechanical femur axis 15 and passing through the center of the articular point. This is a sectional plane assigned to the femur.
- the tool 2 is assigned an instrument level 17. This may be, for example, a longitudinal center plane.
- the shaft is, for example, oval-shaped with a long and a short axis, the longitudinal center plane runs along the long axis and in the longitudinal direction of the shaft.
- the femoral neck 19 which bears on the stem 18 and carries the joint ball 20, likewise extends in the longitudinal center plane of the femur implant, as shown in FIG but also be provided that this connecting arm encloses an angle relative to this plane.
- the femoral neck is not in the longitudinal center plane of the instrument, but in the plane defined by the connecting arm between the shaft and ball joint level, and this forms the instrument used by the data processing system instrument level.
- the data processing system receives from the navigation system in each case the position data of the tool 2 and calculates therefrom the position of the respective instrument plane and further the section line 21 of the instrument plane 17 and the femoral transverse plane 16.
- the display shows this section line in the femoral transverse plane 16, also the center point M. the joint ball 20.
- this cutting line 21 passes through the center M of the joint ball 20, the tool 2 or the femoral implant is correctly oriented, namely, it is ensured that the instrument plane passes through the center of the joint ball.
- the surgeon knows he has to move or turn the tool or the femoral implant laterally to reach the desired position.
- a top view or a horizontal cross-sectional view of a pelvis is displayed on the screen 13, this pelvis representation 23 can be schematic and does not require the anatomical data of the patient, it merely serves to indicate to the surgeon that the midpoint M is also at the same time the center of the joint ball receiving joint socket.
- this joint socket 22 is visible in the sectional view or in a transparent representation.
- the pelvis representation 23 is arranged so that the center of the joint socket coincides with the center M of the joint ball 20.
- the femoral transverse plane will not coincide with the cutting plane resulting in a horizontal cross-sectional view of the pelvis passing through the hip joint centers.
